Who makes Devon Motorcycles, Inc. engines?

US EPA certification records name Jincheng Corporation as the engine manufacturer for Devon Motorcycles, Inc. across 2007–2008.

Will parts from another brand fit my Devon Motorcycles, Inc.?

A shared factory and engine size makes another brand a strong candidate, but it does not prove the part numbers match. These machines are assembled from multiple component suppliers, so measure the part you have before ordering a replacement.

What the Devon Motorcycles filings say about the engines

Every Devon Motorcycles filing on record is carburetted — 4 certificate rows, 2007 to 2008, and not one fuel-injected engine among them.

The engine codes on Devon Motorcycles' test vehicles —just one across the filings — are led by JC162MJ. The code is stamped on the crankcase and is a better search term than the badge.

1 of the 4 filings are 50-state (California-legal); the other 3 were 49-state only.

Rated power across the range runs from 1.8 kW to 8.1 kW (about 2 to 11 hp).

The vehicle builder named on every row is Jincheng Corporation.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
